Comparative analysis of tissue damage and inflammatory response for transoral laser microsurgery versus open surgery in the management of early-stage laryngeal cancer.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThis study aimed to analyze the perioperative dynamic changes of tissue damage and inflammatory response markers, and to determine whether these differ between transoral laser microsurgery (TLM) and open surgery (OS) in early-stage laryngeal cancer.
methodsIn a randomized controlled study conducted at the 2nd Affiliated Hospital of Harbin Medical University, four hundred patients with early-stage laryngeal cancer were randomly assigned to undergo either TLM (n = 200) or OS (n = 200) treatment. Blood samples were collected at various time points: upon admission, immediately before surgery, 2 h post-surgery, 24 h post-surgery, 48 h post-surgery, and one-week post-surgery. These samples were analyzed for a range of biomarkers indicative of inflammatory processes and tissue damage, including high-sensitivity C-reactive protein (hs-CRP), white blood cell count (WBC), platelet count, interleukin-6 (IL-6), cortisol, creatine kinase (CK), and tumor necrosis factor-alpha (TNF-α). The analysis of these markers aimed to provide insights into the physiological responses and potential tissue-level changes in the study participants. Additionally, surgical information, perioperative complications, and 2-year postoperative follow-up Overall Survival were meticulously recorded and analyzed.
resultsThere were no significant differences in baseline characteristics between the two groups. Analysis of clinical and perioperative data revealed that patients who underwent TLM experienced shorter operating times, reduced hospital stays, and lower estimated blood loss and Visual Analog Scale (VAS) scores compared to those in the OS group. Additionally, the rates of general anesthesia, as well as complications such as hemorrhage and infection, were lower in the TLM group. Postoperative measurements indicated that hs-CRP, WBC, IL-6, and cortisol levels were significantly lower in the TLM group at several time points. However, there was no difference in the two-year Overall Survival between the two groups.
conclusionThis study demonstrated that in early-stage laryngeal cancer, TLM treatment results in a reduced inflammatory response, less tissue damage, and lower stress levels, as indicated by decreased levels of hs-CRP, IL-6, and cortisol, compared to OS treatment. These findings suggest that TLM has the potential to facilitate a quicker recovery and improve patient-reported outcomes compared to OS.
